Speeding fines in France

Foreigner or not, speeding is punishable by law (usual speed limits). Having a french driving licence or not, driving a vehicle with french driving plates or not, will make a difference in the outcome:
- You are arrested by the police or gendarmerie for moderate speeding. Fine to be paid on the spot. Points lost if french driving licence.
- You are arrested by the police or gendarmerie for inmoderate speeding (in excess of 50km/h). Fine to be paid, licence confiscated, vehicle might be impounded.
- You are caught speeding by a speed camera but not arrested with a foreign registered car. You are not likely to ever have to pay the fine, except if you are from Luxembourg. For now. Check here for more.
